CELLULAR-BOARD MACHINE.

Specification of Letters Patent. Patented Alig. 13, 1912.

Application filed April 12, 1911. Serial No. 620,535.

To all whom it may concern."

Be it known that I, THOMAS H. TAYLOR, a subject of the King of Great Britain, and a resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Cellular- Bo-ard Machines, of which the following is a specification.

This invention relates to machines for manufacturing cellular board, and particularly to means for backingthe strip of cellular board and for cutting the finished strip into desired lengths.

An object of my invention is to produce improved means for drying the cellular board, after thebacking strip has been se-' cured in place. I

A further object is to produce improved means for drying the finished strip, and for cutting it into desired lengths.

These'and other objects I attain in a machine embodying the features herein described, and illustrated in the drawings acrattle illustrated in Fig. 1.

. together, and applies heat to the strips dur- I it is relieved of the ing the time that they are subjected to pressure.

One of the features of my invention is to produce means for heating the strip, after pressure imposed on it by the backing machine while it ispassing over the cutting table, so that the'steam and moisture may freely escape from the stripand the strip may be more thoroughly dried, beforeit arrives at the cutting knives.

The apparatus illustrated as an embodiment of my invention is adapted to secure a backing strip 'on a strip of corrugated board and to cut the finished boards into desired lengths. After the glue is applied to the strip of corrugated paper, and thebacking strip is in place on the paper, the paper The table is arched for the is fed to the backing machine, where it travels across a heating plate 3, and is subjected to sufiicient pressure to secure the backing strip in place. The heating plate consists of a flat metal plate, below which a series of steam coils 4 are located. The strip is moved across the plate, by means of a heavy endless belt 5, which'runs over two pulleys, and is so located that the lower leg of the belt contacts with the strip located on the plate. Any suitable means may be employed for driving the'belt- 5. Additional pressure may be applied to the'strip of corrugated board 6 as it passes over the plate, by means of rollers 7, which rest upon the belt, and which may be spaced at equal distances apart along the plate. After the strip 6 has passed across the plate 3, it is passed over an arched cutting table 8 to a knife 9, employed for, cutting it into desired lengths. purpose of providlng an initial arch or bow in the strip located on it, so that the strip will not be crushed, or bent and broken, during the cutting period, when the severed end of the strip is held against forward motion by the knife 9. By providing the arched table, the only effect that the cutting operation has on the strip passing across the table, is to increase the arch or curvature of that portion of the strip on the table, during the comparatively short time that the forward end 'of the strip is checked by the cutting knife 9.

I have provided an arched cutting table, whichconsists 'of a series of steam coils, across which the cellular board 6 passes on its way to the knife, after it has passed over the plate 3. The steam coils illustrated, consist of parallel steam pipes 10, which extend transversely across the path of the strip of cellular board 6, and which are' connected together in series by means of U-joints 11. The coils are supported on arched metal strips 12, located near opposite ends of the pipes, and which are supported at their centers by a standard 13. One end of each strip is supported bythe frame portion 13 of the backing machine, and the other portion is supported by the frame 14 of the knife 9. Steam is. delivered to the central coil of the arched series through a pipe 14, which is provided with a valve 15. Each end of the series of coils connect with a discharge pipe 16, through a separate branch pipe 17. With th1s arrangement, steam is delivered to the coils of the cutting table, and the steam and highest coil of the arched series. and-the frame 14. The knife is actuated by an ec-' centric rod 18, which is actuated by a pulley 19. T he pulley may be driven by' any suitable means, as, for example, a belt 21, which is driven by the operating mechanism of the belt 5.

\Vith my invention, the finished cellular board contacts with the hot surfaces of the the strip is moisture escapes freely while Under these traversing the cutting table.

' conditions, the cellular board is more thoroughly dried, and consequently the knife 9 can easily cut it into desired lengths.

'VVhat I claim is 1. A cutting table for a machine of the character described comprising an arched C series of heating coils, located one beside the other.

2. A cutting table for machines character described comprising an series of heating coils.

3. A. cutting table for machines of the character described comprising an arched series of steam coils, a steam supply pipe of the arched communicating with the central coil of said senis, and a-discharge pipe communicating with each end of said series.

4. In combination with a cellular board backing machine, a cutting knife, and an arched cutting table located between said knife and said machine and comprising a series of steam coils over which the board 10 sses.

5-In combination with a cellular board backing machine, a cutting knife, and a cutting table located between the machine and the knife and comprising an arched series of steam coils, a steam supply pipe communicating with the central coil of said series, and a discharge pipe communicating with each end of said series.

6. In combination with a cellular board backing machine, a cutting knife, an arched cutting table located between said knife and said machine, and means for heating the surface of the cutting table.

7. In combination with a cellular board backing machine, a cutting knife and a cutting table locatedbetween the knife and the machine and over which the board moves in passing to the knife, and means for heating the board as it passes over the table and thereby permitting the free escape of moisture therefrom. 1)
